MW_VERSION

Wersja MediaWiki:

≥ 1.35

Począwszy od wersji MediaWiki 1.35, zmienna $wgVersion została uznana za przestarzałą i została zastąpiona stałą MW_VERSION.
It is also available in MediaWiki 1.31.7, 1.33.3 and 1.34.1, though this should not be relied on as its presence is required for some release tools.
$wgVersion will continue to function the same as before in those versions.

Przykładowy kod

If you're implementing a new feature that only works in MediaWiki 1.19 or later, but you want to maintain backwards compatibility, you could use a test such as the following:

$oldVersion=version_compare($wgVersion,'1.18','<=');if($oldVersion){# Do stuff for MediaWiki 1.18 and older}else{# Do stuff for MediaWiki 1.19 and newer}

However, it is typically recommended that you use feature detection to see whether the method or class you wish to use is available instead of depending upon raw version strings.
